Original Set Indicator
If any dirt on the original scanning area is detected when the originals are placed
in the feeder, the following screen appears. Even though streaks may appear on
the copies, you can continue to scan your documents by pressing [Done].
It is recommended, however, that you open the feeder, clean the scanning area,
and then close the feeder. The following screen will not appear once the
scanning area is clean.
For instructions on cleaning the original scanning area, see "Routine Cleaning,"
on p. 7-55.
If you still find streaks on the output after the original scanning area has been
cleaned, specify the Remove Background mode to erase the streaks. (See
